This paper presents a complete PSpice model of an ultrasound single-element transducer,
including electrical and mechanical matching as well as the focusing lens. By using this
model, it is possible to obtain a relation between the electrical driving source and the
acoustic velocity on the transducer surface. This boundary condition then allows the acoustic
field to be calculated by numerical methods. Experimental data obtained with two different
transducers are in good agreement with results predicted by the related models.
